rI'his invention relates to plows and more particularly to a reversibleplow adapted to be attached to a tractor and having two plow sharesarranged for right hand and left hand operation so as to plow in eachdirection.

` An object of the Vinvention is to provide a reversible or `right andleft hand plow,` the moldboards of'which are mounted to swing on alongitudinal pivot and having "a novel mounting construction and frameas well as control arm or `a leveryso that when one of the moldboards isin the ground, and thetractor pulls the plow the length of the ield, theoperator upon turning the tractor around to proceed in the oppositedirec tion, releases'the control arm and the weight of the plow which iselevated pulls the control-arm and plows to the opposite side, so thatthe previously raised plow is lowered into the `ground and thepreviously arranged plow in the ground isv4 elevated. t Other objectsand advantages reside in the details of construction and operation asmore fully hereinafter described and claimed. reference being hadtotheaccompanying drawings forming part hereof, wherein like numeralsrefer to like parts throughout, and in which: i

The reversible plow of the present invention is indicated at 26 andincludes a pair of drawbars or linksv28 pivoted for vertical swinging4movement on opposite sides of the differential housing as at 30 onsuitable studs or bosses 32. Short arms 34 are secured at one of `theirends to the `crank shaft 24 and pivotedat their opposite ends as at 3Gto the upper ends of arms 38which are in turn pivoted as at l0 to thelinks 28. [The links 28 are adapted to be raised and lowered by aconnectionto the power take-off as will. be de'- scribed hereinafter.Adjustably pivoted as at 4.2 to the upper rearportion of thedifferential hous`- ing I3 is a link 414 whichis inturn-pivoted as at i6between the upper ends of a pair of` spaced parallel upright bars 48;The Aupright bars'are rigidly secured' at their lower ends to the plowframe'll and reinforced atthe connection with the frame with appropriate`webs or gussets 52.

The plow frame includes a transverse 'horizonw 'tal drawbar 54 securingthe bars 48, the 'drawba-r 54 including reduced ends 55f upon `which arepivoted the links 23, the latter being retained thereon by suitableCotter pins 53; The `trans-- verse bar 5d securesan arcuate enlargedsegment or bowed bar 50 provided with circuinferentially spacedapertures 62 for adjustably `receiving headed bolts 64 and closure nutsG6 for securing U-shaped catches orkeepers 68 adaptedto selectively hold`an operating lever l0 to be de'- scribed later. By `means of theapertures B2,

`the'bolts and' nuts 64 and 66 and the keepers 68,

the two positions ofthe operating lever 1Q may be circumferentiallyadjusted on the `segment bar E0 as will be readily apparent to thoseskilled in theart."

Ri'gidly secured at one of its ends centrally to the transverse bar`54`is a 'shaft 'l2 upon which is journaled a sleeve 1li held againstlongitudinal relative movement on the shaft byan appropriate key or pin16.

A further headed bolt 96 extends through the aperture82 and each of the plow beams and also receives a closure nut 08. An L-shaped lug is secured to each arm of the V- shaped plate '|8 adjacentone of the slots 80 and includes a set screw |02 threaded through onearm thereof and adapted to abut an edge of each of the plow beams. Thuswhen the nuts 04 and 98 are loosenedtheset screw |02 may b eturned tourge each plowbeam to the Vdesired angular position on each arm of theV-shaped plate, the plow beam pivoting about the central bolt 8,0.Retightening the nuts will retain theplow ,beams and moldboards inproper position on the V-u shaped plate.
